876cc68311 tools:acrn-crashlog: Change the algorithm of generating event key
Acrnprobe is using SHA to generate ids for events. These ids are only used
to index events, not for cryptographic purpose.

This patch unify the generating algorithm of short and long ids to
SHA256.

41b39c5e1f tools: acrn-crashlog: Defer the vm events processing when failed
In the original design, acrnprobe marked all handled VMs'events as "synced"
in file vmrecordid(this patch changes the name to VM_eventsID.log).
Currently, the Android log events are not logged if the first attempt at
reading collecting them from the VM fails. This patch changes the logic
so that the acrn-crashlog tool will retry continuously.

This patch defines different tags for handled VMs'events, and only marks
VMs'events "synced" after it returns successfully.

3e8e607d5b tools: acrn-crashlog: Fix potential issues under acrnprobe
This patch is to fix potential issues, which are reported by static
analysis tool, for acrnprobe.

Changes:
1. Check the return value of sender_id() and get_sender_by_name(),
   since it could be -1 or NULL.
2. Remove the parameter len from create_event, take parameter path
   as a NULL-terminated string as default.
3. Modify for_each_* functions to avoid overflow.

e86da09974 tools: acrn-crashlog: main thread of acrn-crashlog/acrnprobe
This patch implements the main thread of acrnprobe.

As a log collection mechanism to record critical events on the
platform, acrnprobe provides the following features:
1. detect event.
2. analyze event and determine the event type.
3. collect information for the detected events.
4. archive these information as logs, and generate records.
